ASUS X550CA working AppleHDA DSDT patch

[pokiron]

Hi to all.

 

I have an ASUS X550CA laptop. I already installed OS X 10.10 without any errors. first here are the specs:

 

Processor               : Intel® Core™ i3-3217U Processor (3M Cache, 1.80 GHz)

Graphics Processor(GPU) : Intel® HD Graphics 4000 

Chipset                 : Intel® HM76 Express Chipset

Hard disk               : HGST 500GB 5400rpm HDD 

RAM                     : 4GB DDR3 1600 MHz SDRAM

Wifi                    : Atheros AR9485 Wireless Network Adapter

LAN                     : Realtek RTL8168/8111 PCI-E Gigabit Ethernet Adapter

Audio                   : Realtek® High Definition Audio ALC277

USB 3.0                 : Intel Panther Point PCH - USB 3.0 xHCI Controller 

Touchpad                : Elantech Touchpad v4 Hardware

Webcam                  : USB2.0 UVC HD WebCam

Card reader             : Realtek RTS5289 PCI-E Card Reader

Optical Drive           : HL-DT-ST DVDRAM GT51N SCSI CdRom

Battery                 : 6Cells 4700 mAh 50 Whrs

 

 

 

 

I just want to know how to patch my DSDT to work with native AppleHDA kext. I saw other threads and reported successful patching and I want my laptop to be vanilla as much as possible. I have attached my system-dumped DSDT.aml and Clover config.plist if you want to view it.

 

 

Windows reported my Realtek codec is ALC277

 

 

Many thanks.
